What is a whole house fan?

Whole house fans can keep your home cool most of the year in most climates and reduce air conditioning costs. It works by pulling the air through open windows and then into and out of the attic. The Department of Energy (DOE) reports that whole house fans are the most cost-efficient way to cool your home.

How does it work?

Anytime it is cooler outside than the inside of a home, the QuietCool whole house fan system will work effectively. When the QuietCool whole house fan is turned on, the fan will pull the cooler outdoor air into your home, through your windows, across your living space, into the attic, and out the attic vents replacing the hot stale air. This helps cool the home and attic by up to 30 degrees. Watch Video

Which one should I get?

The QuietCool Stealth and Trident are identical except for the motors. The Trident uses a PSC motor & the Stealth uses a EMC motor.

A PSC or permanent split capacitor is a type of motor that is designed to do two things. It turns on and it turns off. The electrical output of the motor is not controllable and there are no speed variances to control. Because the motor operates at a constant speed, the use of energy is a constant and efficiency is lost.

ECM or electronically commutated motors save energy and improve the efficient movement of air through your unit. ECM motors allow for variable speeds which can correspond to the unit's call for air flow. Typically, an ECM motor will slowly come on and increase the speed of the fan gradually as opposed to just coming completely on at startup.
